Shibuya, Japan

A one-day hackathon in Shibuya for teams building with OpenAI's newest DevDay releases. Participants enter in pre-formed teams of two to four and work with Codex CLI or the Codex App; other coding agents, or OpenAI models reached through them, are not allowed. Projects must be deployed publicly, such as to ChatGPT Sites, Cloudflare Workers or Vercel. The day moves from briefing and team formation to hacking, pre-judging and ten demo pitches, then awards and a networking hour. Organizers are Codex Ambassadors; CyberAgent provides the venue.
